环境包含 OS X 10.6.8 服务器和 OS X 10.8.2 客户端。DHCP 在服务器上运行，租约时间为 1 天（86400 秒）。系统日志中每 2 小时记录一次 DHCP REQUEST/ACH 消息（不是预期的 1 天间隔）。请参阅下面的日志“服务器日志”。
在客户端。我检查了 en0 接口的 var/db/dhcpclient/leases 内容。这是唯一启用的接口。结果符合预期。LeaseLength 键的值为 85536 秒（假设它将从 LeaseStartDate 开始递减）。请参阅下面的文件“var/dv/dhcpclient/leases”。
任何关于导致此行为的原因的见解都将不胜感激。谢谢！
